Laproscopic Urology Cystectomy:

Cystectomy is a surgical procedure that removes all or part of the urinary bladder, the muscular organ that collects urine from the kidneys for excretion at a later time. Partial or segmental cystectomy removes part of the bladder; simple cystectomy removes the entire bladder; and radical cystectomy removes the bladder as well as other pelvic organs or structures.

Description

Partial cystectomy

During partial or segmental cystectomy, only the area of the bladder where the cancer is found is removed. This allows for most of the bladder to be preserved. Because the cancer must not have spread to the bladder muscle and must be isolated to one area, partial cystectomy is only used infrequently for the patients who meet these select criteria.

The patient is first placed under general anesthesia. After an incision is made into the lower abdomen, the bladder is identified and isolated. The surgeon may choose to perform the operation with the bladder remaining inside the abdominal cavity (transperitoneal approach) or with the bladder lifted outside of the abdominal cavity (extraperitoneal approach). The cancerous area is excised (cut out) with a 0.8 in (2 cm) margin to ensure that all abnormal cells are removed. The bladder is then closed with stitches. The pelvic lymph nodes may also be removed during the procedure. After the cancerous tissue is removed, it is examined by a pathologist to determine if the margins of the tissue are clear of abnormal cells.

Simple or radical cystectomy

While partial cystectomy is considered a bladder-conserving surgery, simple and radical cystectomy involves the removal of the entire bladder. In the case of radical cystectomy, other pelvic organs and structures are also removed because of the tendency of bladder cancer to spread to nearby tissues. After the patient is placed under general anesthesia, an incision is made into the lower abdomen. Blood vessels leading to and from the bladder are ligated (tied off), and the bladder is divided from the urethra, ureters, and other tissues holding it in place. The bladder may then be removed.

The surgical procedure for radical cystectomy differs between male and female patients. In men, the prostate, seminal vesicles, and pelvic lymph nodes are removed with the bladder. In women, the uterus, fallopian tubes, ovaries, anterior (front) part of the vagina, and pelvic lymph nodes are removed with the bladder. If the surgery is being performed as a treatment for cancer, the removed tissues may be examined for the presence of abnormal cells.

Urinary diversion

Once the bladder is removed, a new method for excreting urine must be created. One commonly used approach is the ileal conduit. A piece of the small intestine is removed, cleaned, and tied at one end to form a tube. The other end is used to form a stoma, an opening through the abdominal wall to the outside. The ureters are then connected to the tube. Urine produced by the kidneys flows down the ureters, into the tube, and through the stoma. The patient wears a bag to collect the urine.

For continent cutaneous diversion, a pouch is constructed out of portions of the small and large intestine; the ureters are connected to the pouch and a stoma is created through the abdominal wall. Urine is removed by inserting a thin tube (catheter) into the stoma when the pouch is full. Alternatively, a similar pouch called a neobladder may be created, attached to both the ureters and the urethra, in an attempt to preserve as close to normal bladder function as possible.

Recovery :

The medical team will discuss the procedure and tell the patient where the stoma will appear and what it will look like. The patient will receive instruction on caring for a stoma and bag. A period of fasting and an enema may be required.

Post Care :

After the operation, the patient is given fluid-based nutrition until the intestines begin to function normally again. Antibiotics are given to prevent infection. The nature of cystectomy means that there will be major lifestyle changes for the person undergoing the operation. Men may become impotent if nerves controlling penile

In a cystectomy with ileal conduit, an incision is made in the patient’s lower abdomen (A). The ureters are disconnected from the bladder, which is then removed (B). They are then attached to a section of ileum (small intestine) that has been removed and refashioned for that purpose (C). A stoma, or hole in the abdominal wall, is created at the site to allow drainage of the urine (D).
erection are cut during removal of the bladder. Infertility is a consequence for women undergoing radical cystectomy because the ovaries and uterus are removed. Most women who undergo cystectomy, however, are postmenopausal and past their childbearing years.

Patients are fitted with an external bag that connects to the stoma and collects the urine. The bag is generally worn around the waist under the clothing. It takes a period of adjustment to get used to wearing the bag. Because there is no bladder, urine is excreted as it is produced. The stoma must be treated properly to ensure that it does not become infected or blocked. Patients must be trained to care for their stoma. Often, there is a period of psychological adjustment to the major change in lifestyle created by the stoma and bag. Patients should be prepared for this by their physician.
